WESTFIELD, Ind. -- In the hallways at Westfield High School, a picture of the girls basketball team hangs with text that reads "Unfinished Business."
They got to work Wednesday night, knocking off defending state champion North Central 61-44 to move on to the Class 4A Sectional 8 semifinal.
They next play Carmel, which beat Fishers 60-49 in the evening's second game.
A year ago, the Panthers (12-8) beat the Shamrocks (19-2) in the sectional on their way to a 4A state title.
This time, Westfield got revenge. Shamrocks center Jenn Anderson said they were looking forward all week to meeting the Panthers again.
"Every day in practice, that was our motivation," Anderson said. "We knew we were going to have to come out from the gate and go. We executed what we needed to do and we came out and won."
Anderson led the way with 18 points and Kayla Brown scored 17 for the Shamrocks, creating a two-headed monster that the Panthers couldn't overcome.
"(Brown) and I know that we have to show up to every game and if we don't, the team's going to struggle," Anderson said. "Tonight, both of us worked hard, we did our best and helped the team win."
The Shamrocks held the Panthers to just three points in the second quarter and started a 13-0 run that stretched to the beginning of the third quarter.
Anderson made two free throws to spark the run midway through the second quarter. Brown added two free throws and blocked a shot, then scored a layup to give Westfield a 22-14 lead.
"She's 6-foot-2 with quickness and length," Westfield coach Shane Sumpter said. "When she's making shots, it makes it extremely difficult to play her."
Later, Brown drove to the basket and scored to give the Shamrocks a 26-14 halftime lead.
Westfield's Taylor Davis hit a 3-pointer at the start of the third quarter to give the Shamrocks a 29-14 lead before Penny Ingram scored to end Westfield's run.
"Offensively, we just couldn't get anything going," North Central coach DeeAnn Ramey said. "Our shots weren't falling; we were even missing close shots inside. Offensively, we struggled."
Anderson and Brown each scored at the start of the fourth quarter to give the Shamrocks a 45-23 lead with 7:14 to play, and Westfield led by nearly 20 points the rest of the way.
In Carmel's win over Fishers in the second game, J.J. Williams scored 31 points to lead the Greyhounds.
Carmel went on a 5-0 run in the fourth quarter to take a 50-41 lead and held on the rest of the way.
Kara Gerka had 18 for the Tigers.
